Abstract

High-field magnetizations of R2CuO4 (R-Nd, Pr and Gd) single crystals are investigated up to 36 T at low temperatures. Nd2CuO4 shows two anomalous phase transitions at 2.2 and 4.2 T along the [100] direction. The keyword to solve these transitions is the staggered field due to the Cu spin. Pr2CuO4 shows weak linear magnetization reflecting the singlet ground state of the Pr ion. Gd2CuO4 shows an anomalous but systematic multistep magnetization with a magnitude of each step of about 10-3μB per Gd ion in the c-plane beside the typical antiferromagnetic magnetization with small anisotropy. The origin is not clear.
